Question 1 In the figure, a 103 g ball on a 66.6 cm rope is swung in a vertical circle about a point 255 cm above the ground. If the ball is swung at the slowest speed where the ball goes over the top of the circle without the rope having any slack and the rope is released when the ball is at the top of the loop, how far to the right does the ball hit the floor? Question 2 A 4.46x105 kg train is stopped at a station. The train must go around a 121 m diameter corner right after it leaves the station. As the train leaves the station it provides a constant forward force of 1.25x10 N. What is the train's acceleration after 19.0 s
